IGS Tubecore Vari Mu Compressor

Mastering Edition

Tracking Edition

The structure is based on the Vari Mu solution, where compression is achieved using the "remote cut-off" or re-biasing of a vacuum tube. The major difference between the Tubecore and it's archetyps is that the construction is mounted on a double layer PCB instead of the point-to-point solution. Concentrating the circuit on the PCB reduces noise and stablizies the parameters. The Tubecore is a 2U unit. The audio path is fully symetric from input to output. The input and output are equiped with separating transformers. The mastering version has a single set of controls manipulating both channels. Specification:
